ROAD DRAG.

Application filed February 7, 1822.

To all whom it may concern:

Be it known that l, EDWARD M. OnToN, a citizen of the United States,residing at Sandstone, in the county of Pine and State 6 of Minnesota,have invented certain new and useful Improvements in Road Drags, ofwhich the following is a specification.

This invention relates to road drags, and the main object is to providea simple, ef-

10 ficient and practical drag particularly adaptable for use inconnection with common types of road scrapers and other road machinery.Further objects will be disclosed in the course of the followingspecification and are illustrated in the accompanying drawing, wherein:

Fig. 1 is a top or plan view of a device embodying my invention.

Fig. 2 is a detail sectional view on the so line 2-2 in Fig. 1.

Fig. 3 is an enlarged fractional detail, as seen when looking in thedirection of the arrow A in Fig. 1.

Referring to the drawing by reference characters, B designates a roadscraper blade of any common and well known con struction, secured bybeams C to tl'lBmZtClllDG or vehicle (not shown) carrying it. Pivotallysecured as at D to the beams C is a pair of rearwardly extendingangle-iron beams E to the front ends of which is secured an angle irondrag beam F. A secondary pair of longitudinal beams G are pivotallysecured to thebeams E, as at H, and have a cross beam I (similar to F)secured at their rear ends. The vertical flanges of the beams G and Eengage one against the other, as shown in Fig. 1, and the verticalflanges of the beams F and I extend downward from the front edges oftheir horizontal flanges.

Spacing blocks J are interposed between the rear ends of the beams G Eand their respective cross beams l and F, the object being to permitsaid latter beams to ride over rough roads in such a manner that eithermay fall in relatively higher or lower position than the other (see Fi2). At the rear ends of each of the beams I and F is provided a rigidprong K, which, as the dirt works to the outer ends of said beams, passthrough said dirt with a tendency to remove rocks or other lumpyobstacles therefrom, and push them farther out to the side of the road.

serial No. 534,761.

In the event that the angle of the scraper blade is adjusted to suitchanging road conditions it will be obvious that the angle of the beamsf, F to the road will be correspondingly changed as the beams E and Gare always retained in parallel positions and the bolts which connectsaid beams to the long cross beams I, F act as pivots.

It is further understood that suitable modifications may be made in thedesign and structural features of this device, provided, however thatsuch modifications come within the spirit and scope of the appendedclaims.

Having now therefore fully shown and described my invention, what Iclaim to be new and desire to protect by Letters Patent is:

1. A road drag consisting of a primary pair of parallel longitudinallyarranged draft beams pivotally secured at their front end to a means fordrawing the drag and having a cross beam at their rear-ends, a secondarypair of draft beams pivotally secured to the first mentioned pair ofdraft beams, and having a second cross beam arranged at their rear ends.

2. A road drag consisting of a primary pair of parallel longitudinallyarranged draft beams pivotally secured at their front end to a means fordrawing the drag and having a cross beam at their rear ends, a secondarypair of draft beams pivotally secured to the first mentioned pair ofdraft beams, and having a second cross beam arranged at their rear ends,said primary and secondary draft beams having vertical flangesengageable against each other.

3. In a road drag, a primary pair of draft beams, a secondary pair ofdraft beams pivotally secured thereto, cross beams secured to said draftbeams, and spacers interposed between the cross beams and the draftbeams.

l. In a road drag, a primary pair of angle iron draft beams, a secondarypair of angle iron draft beams arranged parallel with but extendingrearward of the primary beams, said primary and secondary beams havingvertical flanges pivotally secured together, and cross beams secured toand in angular relation with respect to the draft beams.

In testimony whereof I affix my signature.

EDWARD M. ORTON.
